Removable device of traction adapted for any motorized vehicles

ABSTRACT

The present invention is a removable device of traction adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice or mud.

BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The present invention relates to a removable device of traction adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice or mud.

[0003] 2) Description of the Related Art

[0004] A search of prior art records has unveiled the following United States patents:

[0005] 1. U.S. Pat. No. 3,878,988 issued in 1975 to Blais;

[0006] 2. U.S. Pat. No. 5,899,380 issued in 1999 to Beaulieu;

[0007] 3. U.S. Pat. No. 4,281,791 issued in 1981 to Schaaf.

[0008] The patents to Blais, Beaulieu and Schaaf are probably the most relevant. As can be seen, the patents do not show a system or device of traction adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice or mud.

[0009] As is known, the traction aids are used for releasing a car when trapped in snow or ice. In use, the traction aid is placed in front of the tire in the forward acceleration mode and at the rear of the tire for rearward acceleration. When the car is accelerating, the wheels rotate at a high speed. It is by the rotational force of the wheels that the traction aid is swept under the tire. One problem which is often encountered with the conventional traction aids is that it is difficult to control their positioning under the tire. Indeed, when the wheels are rotating at a high speed, the latter tends to completely slide out and hit a part of the car, such as the muffler, the exhaust pipe or the tail pipe and thus severely damaging the same.

[0010] To overcome the above-mentioned problem, the applicant has developped a removable device of traction adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice or mud.

SUMMARY OF THE INVENTION

[0011] The gist of the invention is therefore to provide a removable device of traction adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice, or mud.

[0012] The proposed system shows a removable device of traction comprising the structural bar members and transverse, which are provided with fastening means on which the chains are mounted, and by which the structural bar members are engaged to the structural plate members gripping firmly to the rubber walls of tires.

[0013] A first side of each bar member is mounted and welded to a pricked plate member, which are motionless and gripping firmly to the rubber walls of tires; and the lower end of the other side from each bar member is mounted into a moving part member which is engaged into a structural part member and connected by means of attachment shown here being bolts, washers and nuts, and by which the structural part member is connected to each pricked plate member provided with threaded rods by means of attachment shown here being adjusting and blocking bolts according the width of tires.

[0014] A curved metal bar is inserted into an opening of the moving part member allowing to tighten and grip firmly the pricked plate members provided with threaded rods onto the rubber walls of tires.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to the drawings in more detail, it may be seen that the removable device of traction (A) of the present invention is adapted for any motorized vehicles, allowing to detach oneself when the drive wheels are trapped in snow, ice, or mud.

[0020] As shown in FIGS. 1 to 4, a removable device of traction (A) comprising the structural bar members and transverse (2), which are provided with fastening means on which the chains (1) are mounted, and by which the structural bar members (2) are engaged to the structural plate members (3)(4) gripping firmly to the rubber walls of tires.

[0021] A first side of each bar member (2) is mounted and welded to a pricked plate member (4), which are motionless and gripping firmly to the rubber walls of tires; and the lower end of the other side from each bar member (2) is mounted into a moving part member (6) which is engaged into a structural part member (5) and connected by means of attachment shown here being bolts, washers and nuts (7)(9)(8), and by which the structural part member (5) is connected to a pricked plate member (3) provided with threaded rods by means of attachment shown here being adjusting and blocking bolts (8) according the width of tires.

[0022] A curved metal bar (10) is inserted into an opening of the moving part member (6) allowing to tighten and grip firmly the pricked plate members (3) provided with threaded rods onto the rubber walls of tires.

[0023] Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of claims. 

The embodiments of the invention for which an exclusive property or privilege is claimed, are defined as follows:
 1. A removable device of traction adapted for any motorized vehicles, comprising the structural bar members and transverse, which are provided with fastening means on which the chains are mounted, and by which said structural bar members are engaged to the structural plate members gripping firmly to the rubber walls of tires.
 2. A first side of each said bar member is mounted and welded to a pricked plate member (4), which are motionless and gripping firmly to the rubber walls of tires; and the lower end of the other side from each said bar member is mounted into a moving part member which is engaged into a structural part member and connected by means of attachment shown here being bolts, washers and nuts, and by which said structural part member is connected to a pricked plate member provided with threaded rods by means of attachment shown here being adjusting and blocking bolts according the width of tires.
 3. A curved metal bar is inserted into an opening of said moving part member allowing to tighten and grip firmly said pricked plate members provided with threaded rods onto the rubber walls of tires.
